Dejan B.

Winner of multiple algorithm contests, with 14 years of IT experience. I have a Masters degree in AI & Machine learning. I can prepare you for interviews or exams, by creating a study plan, based on your skills, just for you.

I was told by multiple clients, after they chatted with multiple algorithm mentors here, seeking assistance for implementing or explaining some advanced complex algorithm/data structure, either everyone turned them down, or those mentors refunded their money after wasting them few hours or days.
At the end I was the only person that could help them with more advanced topic.
That is why I am asking for relatively higher price than others.
You can contact any of my previous clients, in my reviews, and ask them yourself about me.

Feel free to message me and request proof of any other credentials.

My biggest strengths are:

• Mentoring people who prepare for coding interviews
• Designing algorithms and data structures (like Leetcode/Hackerrank/Codility)
• Machine learning, reinforcement learning, data science, computer vision

My Master thesis was creating a game agent that plays the FPS video game Doom, using deep reinforcement learning.
I've done a lot of competitive programming, like Hackerrank, Topcoder, International Olympiad in Informatics, ICPC-ACM, Google Codejam and Hashcode.

I was awarded full scholarships all throughout my high school, Bachelor, and Master studies, for my excellent grades and contests performance.
On my Bachelor in Computer Science, I graduated among top 5% in generation.
For my Master in Artificial Intelligence in Netherlands, I was the only student awarded with a full scholarship.

My work experience:

• At the moment I am working on my own e-commerce startup. I developed the backend using Django, created a smart search engine, which pushed my algorithm and data structure knowledge to the limits. I also develop an image recognition system, with computer vision and deep learning, to be able to take a photo of some product in front of you, and the website immediately gives you the wanted product.
• I've done a lot of mentoring and teaching to high school and university students, for algorithm and math exams, as well as preparing them for algorithm contests. I also mentored many junior colleagues at work as well as making presentations in front of the whole company, in the field of machine learning.
• I worked at Tabtale, a mobile game development company from Israel. Used the Cocos 2D game engine in C++, programmed for Android with Java and for iOS with Objective-C.
• Worked in Maxwell Biosystems, startup based as part of ETH-Zurich University in Switzerland. I was doing data science analysis in Python and Matlab, on neuron recordings.
• Worked remotely for a data science startup Slovenia, on various projects: mentoring data science interns, churn prediction in telecom sector, bus arrivals predictions, predicting gamer playing style in a multiplayer game and matching players in teams based on their rank and playing style.
• I was a teaching assistant at university, for the course Advanced Algorithms
